IMPORTANT NOTE ON TERMINOLOGY: The term “network” in this section refers to a wireless
network. In older Totalflow documentation, the term “network” has been used to describe an
Ethernet network. With Wi-Fi support introduced in newer devices, the term applies to either an
Ethernet or a Wi-Fi network. Either type of network will be clearly indicated in the text and
diagrams.
The term “connection” in this section refers to the wireless link established between a wireless
client and an advertised wireless network. The term is not used to refer to a physical connection
as with Ethernet. Nodes on a wireless network can establish logical TCP connections with each
other on the same wireless network. Diagrams depict wireless networks or links with dotted
lines. Solid lines represent physical connections. Lines with arrows in different color represent
communication or data flows.
10.1 Connections supported by Wi-Fi modes
Table 10-1 shows the XIO Wi-Fi modes and the connections they support. Preferred configuration depends
on the number of XIOs, their location in the field, and the access requirements. Wi-Fi is a convenient way
to access XIOs without having to be in proximity with the device. When there are several XIOs, the
optimal configuration is to configure one as an access point and the rest as clients.
Table 10-1: Connections supported by Wi-Fi modes
Wi-Fi Mode Connection Description
Access Point
(AP) [Host Wi-Fi client]-to-XIO Point-to-point connection from a wireless client to XIO.
Wireless client joins the network advertised by the XIO.
Use when there is only one XIO and there are no other Totalflow
devices that can support Wi-Fi Access Point functionality.
Client XIO-to-[XIO Wi-Fi Access
Point]
XIO and other Wi-Fi clients join wireless network advertised by
another XIO configured as an Access Point
Wi-Fi clients can connect to the XIO over that network.
XIO-to-[Totalflow Wi-Fi
Access point]
XIO and other Wi-Fi clients join wireless network advertised by a
Totalflow device configured as an Access Point.
Wi-Fi clients can connect to the XIO over that network.
XIO-to-[Third-party Wi-Fi
Access Point]
XIO joins wireless network advertised by a third-party access
point.
Wi-Fi clients can connect to the XIO over that network.
Access Point
(AP) Bridged [Wi-Fi client]-to-XIO Wireless client joins the network advertised by the XIO.
Wi-Fi clients can connect to the XIO over that network.
10.2 IP parameter configuration
Connections over Wi-Fi networks are TCP/IP based. Each device connecting to a wireless network must
have a unique and valid IP address. IP configuration depends on the Wi-Fi mode. Table 10-2 describes the
IP configuration requirements.
When the XIO is configured as a Wi-Fi Access Point, it can automatically provide IP addresses for Wi-Fi
clients with its DHCP server. Automatic addressing is the preferred option.
Table 10-2: IP parameter configuration
Wi-Fi Mode Configuration Description
Access Point (AP) Default:
192.168.1.1
DHCP Server
available to clients
Wi-Fi clients (up to 10) can obtain their IP addresses from the
XIO if DHCP server is enabled.
Wi-Fi clients can use default XIO address to connect to the XIO.
